Other method takes advantage of the varying conductivities of blood at. different concentrations of blood. In Hemoglobincyanide method hemoglobin is chemically converted to form a cyanmethemoglobin. which is having maximum absorption around 540nm wavelength. The hemoglobin concentration is determined.
I think a good answer to this is under another question here:chemistry.stackexchange.com/questions/35734/â¦ The first answer gives an explanation of how both ozone and oxygen absorb UV. In regards to your second question, there isn't enough ozone (or other UV absorbing compounds) to perfectly screen the Earth's surface. In addition, ozone absorbs only specific wavelengths of UV light, so other UV wavelengths could get through. â Tyberius Mar 4 '17 at 5:41 Although you ask about ozone and UV light, the process is completely general is the same for any molecule, chlorophyll in plants, the dye in your T shirt, ink on paper etc. In the molecule, if the photon has the right amount of energy, it excites an electron to a higher molecular orbital and so forms an excited state.
